[PATCH] test-lib: add the test_bash convenience function

[Jens Lehmann <Jens.Lehmann@web.de>]

Since 781f76b15 (test-lib: redirect stdin of tests) you can't simply put a
"bash &&" into a test for debugging purposes anymore. Instead you'll have
to use "bash <&6 >&3 2>&4".

As that invocation is not that easy to remember add the test_bash
convenience function. This function also checks if the -v flag is given
and will complain if that is not the case instead of letting the test
hang until ^D is pressed.

I was tempted to call that method "run_bash" but after looking around
in test-lib.sh "test_bash" seemed like a better name.
